Origin and history

Mehun-sur-Yèvre Castle, built in the 12th century on a rocky eminence overlooking the confluence of the Yèvre and the Annain, was initially a defensive fortress controlled by the families of Mehun, Vierzon, and then Courtenay-Champignelles. His strategic role made him a seigneurial issue, before he came under royal rule after the confiscation of the property of Robert III of Artois in 1332. The site, already occupied by an ancient oppidum and a wooden castle in the ninth century, was gradually modernized by chestnuts such as Beatrix or Mahaut de Mehun, which made it a place of culture and local power.

In the 14th century, the Duke Jean de Berry (1340–1416), heir to the fief in 1360, undertook a radical transformation of the castle into a sumptuous Gothic palace, entrusted to architect Guy de Dammartin and sculptors André Beauneveu and Jean de Cambrai. The work, which began in 1367 after his English captivity, lasted fifty years, mixing defensive elements (douves, crenellated towers) and luxurious decorations inspired by the radiant and flamboyant style. The castle became a high place in the Cour des Valois, welcoming figures such as Jacques Coeur or Queen Mary of Anjou, and serving as a residence for Charles VII, who died there in 1461 after leading key strategies of the Hundred Years' War, alongside Joan of Arc between 1429 and 1431.

After its peak in the 15th century, the castle was abandoned in favour of the Loire castles, then ravaged by fire (XVI century), the Wars of Religion, and the French Revolution, which reduced it to a stone quarry. The ruins, classified as historical monuments as early as 1840, still reveal today the remains of the transformations of Jean de Berry: double crowned towers, destroyed chapel (of which consoles remain), and fragmentary sculptures. As a municipal property since 1817, the site houses a museum dedicated to Charles VII and has been the subject of archaeological excavations for twenty years, revealing buried elements of its medieval past.

The castle is also famous for its representation in The Most Rich Hours of the Duke of Berry (miniature of the Tentation of Christ, 1411–1414), illustrating its eccentric architecture, between fortress and palace. The duke's partially restored gardens and archaeological collections (squares, ceramics) testify to its historical importance. An annual medieval festival in July continues its memory as a symbol of the transition between the Middle Ages and the Renaissance in Berry.

Prior to the work of Jean de Berry, the site housed about ten successive defensive castles, whose wooden and stone foundations served as the basis for reconstruction. The deep moats and the four towers (including the dungeon) were preserved, while the modifications of the chestnuts, such as Mahaut de Mehun in the 13th century, made it a place of cultivation. The peaceful transmission of the castle by successive marriages (from Courtenay to Valois via Bonne de Luxembourg) allowed its architectural enrichment, before its post-Renaissance decline.

Today, the visible remains date mainly from the reshuffles of 1367–90, with double-walled walls (cut stone and bellows) and arches in cradle or on dogive cross-sections. The main tower houses the Charles VII Museum, offering panoramic views of the region. Despite the deterioration, recent excavations have saved key elements, while the municipality works to preserve it, between historical heritage and tourist attraction.

Future

Currently it is owned by the commune and transformed into a museum dedicated to King Charles VII and his reign.
